Extreme Weather and Climate Change: IPCC 2011 Report

 

 Extreme Weather and Climate Change 2011 IPCC summary report

 

 

INTRODUCTION:

The Special Report for Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX) was a collaborative effort of IPCC Working Group I, which focuses on the physical science basis of climate change and Working Group II, which focuses on impacts, adaptation, and vulnerability, with Working Group II holding the overall responsibility.  More than 80 authors, 19 review editors, and more than 100 contributing authors from all over the world contributed to the preparation of SREX.

QUOTES:

“A hotter, moister atmosphere is an atmosphere primed to trigger disasters,” said Michael Oppenheimer, a Princeton University climate scientist and a principal author of the new report. “As the world gets hotter, the risk gets higher." See the NYT article HERE.

Qin Dahe, Co-chair of IPCC Working Group I, which together with Working Group II was responsible for the development and preparation of the report, said: “There is high confidence that both maximum and minimum daily temperatures have increased on a global scale due to the increase of greenhouse gases.”

A few quotes from the report:

  • There is evidence that some extremes have changed as a result of anthropogenic influences, including increases in atmospheric concentrations of greenhouse gases. (p6)

  • It is likely that the frequency of heavy precipitation or the proportion of total rainfall from heavy falls will increase in the 21st century over many areas of the globe. (p10)

  • Average tropical cyclone maximum wind speed is likely to increase.... It is likely that the global frequency of tropical cyclones will either decrease or remain essentially unchanged. (p11)

  • It is very likely that mean sea level rise will contribute to upward trends in extreme coastal high water levels in the future. (p12)

  • Effective risk management generally involves a portfolio of actions to reduce and transfer risk and to respond to events and disasters, as opposed to a singular focus on any one action or type of action. (p14)

  • The interactions among climate change mitigation, adaptation, and disaster risk management may have a major influence on resilient and sustainable pathways. (p16)
